RICHARD L. MOUL'I'ON, F PROVIDENCE, RHODE ISLAND AUTOMATIC TBAIN- TOPI ING DEVICE.

T 0 all whom it may concern:

Be it knownthat I, RICHARD L. MoUL'roN, a citizen of the United States, residing at. Providence, in the county, of Providence and State of Rhode Island, have invented a new and useful Improvement in Automatic Train-Stopping Devices, of which the following is a specification.

This invention relates to an automatic train stopping device, and the object of the invention is to provide novel and improved means for automatically venting the air brake system of the train upon the setting of tripping means to operative position.

A further object of the invention is to provide novel and improved tripping means for the air brake system venting means, and to otherwise generally improve, simplify and increase the etliciency of the several aforementioned means.

In the drawings-Figure 1 is a perspective view of the invention showing the parts in relative positions on the track and locomotive, the latter parts being shown in fragment. Fig. 2 is an end elevation of the means for operating the air brake. Fig. 3 is a fragmentary side elevation of Fig. 2 parts being broken away, and shown in section. Fig. 4: is a side elevation of the air brake venting valve. Fig. 5 is a section on the line 55 of Fig. 4. Fig. 6 is a front elevation of the tripping means, and Fig. 7 is an end elevation of Fig. (3.

The tripping means consists of a supportint frame that includes a pair of end members l which are centrallv depressed at 2, the ends of the members being suitably attached to the under faces of two or more of the track tie .i transverse plate 3 is secured to the depressed parts 2 of the end Iii" HHS 1. and an arched member 4 overlie the plate 3 and has its ends secured to the Secured to the top of the sitter. arch d member 4: at the ends of said top, are a pair of transverse bars 5 which have one of their ends extending beyond the adjacent side of the member 4- and formed with rounded extremities that provide pivots for the arms (3 and 7 respectively, the arms having brackets 8 bolted thereto. which brackets are perforatei i to receive the rounded eX- The arm 6 has a bracket 9 attached to its lower end, while the arm 7 has a similar bracket 10 attached to its upper endna diagonal bar 11 being pi oted at its ends to the horizontal arms 12.

formed on said brackets, whereby the arms 6 and 7 areconnectcd to move in'unisoit.

Attached to the bracket 9 is an inclined plate 13 to which latter is connected a wire or rod 1%. The arm 7 has its lower end portion extended horizontally at 15 and then extended downwardly at 16, the extremity of the end 16 being connected to a wire or rod 17. The wires let and 17 may be connected to the signal operating levers, or they may be in connection with'the operating mechanism of the signal tower, the wire 1? being for the purpose of moving the parts to inoperative positioin'while the wire 1 L has for its purpose the moving of the parts to operative position. In order to rigidly hold the arms in operative position, a latch is provided which consists of a member 18, which is attached to the plate 3 and which is formed with an outstanding arm 19 that has a right angular end 20 adapted to engagethe arm 6 when the latter is in' operative position depicted in Fig. 0 of the drawings. A. bracket 21 is rigidly secured to the plate 3 and has a guide finger 22 which,

engages the end 16 of arm 7 and prevents any tendency the same may have to movie laterally when said arm is in inoperative position.

The venting means for the air brake systemi'ncludes a valve 23 rotatably mounted in a caslng 24 which latter has a port 25 that i is in communication with the pipe 26 of the 7 air system, the valve having a series of ports which when brought to register with the Patented June 16, 1914.

port 25, allow the air to escape through an outlet port 28 formed in the casing 21. The casing 24 is mounted at 30 from a bracket 29 which latter is connected by end members 29 to the locomotive frame. The ends of the valve are provided with portions 31 of square cross-section which latter are received in apertures of corresponding shape that are formed in the substantially diamond shaped'arms 32.. The. arms 32 are secured to the ends 31. of the valve by means of collars 33. The arms 32 are inclined outwardly away from each other, at their lower ends and are connected by means of across rod 34. The bracket. 29 1s provided with end members 35 which have downwardly extending extremities 36 that are slotted to receive the arms 32. Latching devices 37 are attached to the parts 36, as shown in Figs. .2 and 3 in order to hold thearms 32 in raised position after actuation of the latter.

In operation the arms 6 and 7 are moved to raised position by movement of the wire 14, and in this position should a train attempt to pass the arms, the cross rod 34 will contact with said arms and will be moved 'upwardly, carrying with it the arms 32,

which latter will be engaged with, and held in locked position by the latching devices 37. The stated movement of the arm 32 causes the valve 23 to be-movedto venting position, withvthe result that the air. brakes will be set and the train brought to'a stop. It will furthermore be seen that each of the operat ing cables or rods 14- and 17 extend out from same side of the frame 1, and that the arms 6 and 7 are movable laterally of the track.

Having thus described my invention, I

- claim as new and desire to secure by Letters Patent 1. In a device of the tppe set forth, a frame, including end mem ers having central depressed portions, a transverse plate connected to said depressed portions, an arched member secured at its ends tosaid plate, a pair of arms pivoted intermediate their ends to the top of said arched member, a diagonal rod pivoted to the top end of one arm and to the lower end of the other arm,

an operating wire connected to the lower end of the last named arm,- the first named arm havingv its lower end iortion rovided witha horizontal portion t at terminates in RICHARD L. MOULTON.
